SPECIFICATION forming part of Letters Patent No. 407,597, dated July 23,1889.

Serial No. 220,467. (No model.)

To all whom it may concern.-

Be it known that we, CHARLES H. KNOWL- TON and BENJAMIN F. MEYER,citizens of the United States, and residents of Camden, New Jersey, haveinvented certain Improvements in Looms, of which the following is aspecification.

Our invention relates to that class of looms in which a fixedshuttle-race and reed are IO combined with an independent comb forbeating up the weft-thread, the object of our invention being toconstruct a high-speed 100111 of this class in which a large number ofshuttle-boxes can be used.

In the accompanying drawings, Figure 1 is a side view of the lower partof a loom embodying our invention; Fig. 2, a side view of the inner partof the upper portion of the loom, looking in the direction of the arrow,Fig. 3, and illustrating a feature of our invention; Fig. 3, atransverse section of said upper part of the loom on the line 1 2, Fig.2; Fig. 4, a front view of part of the loom with some of the partsbroken away to show those behind; Fig. 5, a diagram showing themechanism for operating the beatingl-up comb, and Fig. (5 a detachedView of part of the shuttlebox-operating mechanism. Fig. 7 represents amodification in the construction of part of 0 the loom.

A represents part of one of the side frames of the loom; B, thecrank-shaft, adapted to suitable bearings thereon, and D a cam-shaftadapted to similar bearings. The shuttlerace F and the reed F carriedthereby are immovable, the shuttle-race forming part of the fixed frameof the loom and the beating up of the weft-thread being effected by acomb 00, which is carried by a lathe G, pivoted to one arm of a lever G,the other arm of which carries an anti-friction roller j, acted upon bycams D 011 the shaft D.

A pin a on the lathe G is connected to a fixed pin a on the frame oftheloom by means of links I) b, the jointed ends of which are connectedby a third link 0 to the pin 0 of a crank on the shaft B, the result ofthis mechanism being that as the shafts B and D are rotated a combinedlongitudinal vibrating and vertical reciprocating movement substan- 5 otially in the path shown by the dotted .line 00 in Fig. 5 is imparted tothe comb as, so that after a filling-thread has been laid across theopen shed by .the passage of the shuttle the comb will riseinto the shedbehind said fill ing-thread, and will then be carried forward,

so as to beat it up, after which the comb will descend to a point belowthe shed and will be retracted to the starting-point, ready to beat upanother thread. This construction is substantially similar to that shownin the patent of J. C. Duckworth, No. 172,097, January 11, 1876, inwhich, however, the invention is illustrated as applied to asingle-shuttle loom.

In the weaving of certain classes of fabrics (ingrain carpet, forinstance) it is necessary to employ a large number of shuttles, andDuckworth, in adapting his loom for the performance of work of thisclass, adopted the construction shown in his patent, No. 211,718,January 28, 1879. In the loom shown in said patent two sets ofshuttle-boxes, one in advance of the other, on each side of the loomwere employed, and the shuttle-race and reedwere vibrated soas to bebrought into line with either set of shuttle-boxes; but thisconstruction is objectionable, not only because of the duplication ofthe picking mechanism at each side of the loom which it necessitates,but also because it sacrifices one of the main advantages of theoriginal Duckworth loomthat is to say, the fixed shuttlerace and reed. I

In carrying out our invention we discard the construction shown in thelast-mentioned patent, No. 211,718, and use in connection with thestationary shuttle-race and reed of the original Duckworth loom shuttlebox mechanism of a character substantially similar to that shown inMurklands patent, No. 0 97,106, November 23, 1869, for we find that weare in this way enabled to attain theadvantages of a loom constructed asin Patent No. 211,718, so far as regards the employment of a largenumber of shuttles, without the com- 5 plexity, difficulty of working,and other objections which are inseparable from the construction shownin said Patent No. 211,718,

while at the same time we overcome certain objections to which theMurkland shuttlebox arrangement is subject when it is used in connectionwith a vibrating lathe, as usual.

The shuttle-box slide 11 is guided on a slightly-inclined fixed sideframe I, and is operated by a shuttle-box cam J, carried by a shaft J atthe rear of the loom, said cam acting through the medium of a lever I,which is connected by a link d to an arm d, guided on a rod (Z of theframe and acting upon the lower end of a spring 6, which is coiled rounda guide-rod 6, carried by and projecting downward from the shuttle-boxslide H, the

upper end of said spring bearing against said slide and serving as themedium through which the movement of the arm (1 is imparted to the same.

The upper shuttle-boxes y of the set are secured directly to the upperend of the boxslide H; but the lower boxes 3 are carried by a cylinderII, having trunnions f, adapted to bearings on the slide. As the slide His reciprocated vertically, therefore, the cylinder H may be rotated inone direction or the other by the engagement of pins g on said cylinderwith one or other of the notched arms h h of a forked lever L, which ishung to a suitable stud near the base of the loom, the lever being movedso as to throw either of its arms into engagement with the pins g, or soas to adjust the arms to an intermediate position in which both are freefrom engagement with said pins. These movements of the lever L aredetermined by a dictating-lever K, hung to a pin on the fixed frame ofthe loom and connected to the lever L by a link K, said dictating-leverhaving recesses 2', with one of which engages one arm of a locking-leverM, hung to a fixed stud, the other arm of said lever being-acted upon bya spring M, so that the lever, by engagement with one or other of therecesses 1', serves to retain the dictating-lever in any one of thethree positions to which it may be adjusted.

By the use of shuttle-box mechanism of this character we are enabled toemploy the desired large number of shuttles without resorting to thecomplicated, expensive, and troublesome construction shown in theDuckworth patent of 1879. In operatingthe usual Murkland loom it hasbeen found necessary to limit the speed of the same in order to preventoverrunning or derangement of the box-cylinder H, and this objection weconceive to be due to the vibration of the lathe, which, in the ordinaryMurkland loom, carries said box-cylinder. In ourimproved loom thisobjection is entirely overcome, and we are enabled to run the loom at amuch higher rate of speed than an ordinary loom with the Murklandarrangement of shuttle-boxes, this advantage arising from the fact thatin our loom the bearings for the shuttle-box slide are perfectly rigid;hence, whatever the speed at which the loom is run, there can be no suchjarring of the box-cylinder as would have a tendency to cause the sameto overrun or would interfere with the proper engagement of the notchedarms of the lever L with the pins of said cylinder. It was also found inoperating the Murkland loom that when the loom was thrown out of gear bythe action of the weft-fork the movement of the loom was not arrested asquickly as was desirable, because of the difficulty of overcoming themomentum which had been acquired by the swinging lathe and its heavybox-cylinder. This objection, it will be evident, is entirely overcomein our loom.

\Ve are aware that it has heretofore been proposed to use in a loom ashuttle-box slide and cylinder adapted to bearings on the fixed frame ofthe loom, and we may refer to the patent of Hickey and Miles, No.192,580, July 3, 1877, as an instance of such construction; but in.thiscase, as in the construction shown in the Duckworth patent, No. 211,718,the shuttle-race moves back and forth, the Hickey and Miles loom beingeven more objectionable than the Duckworth loom in this respect,

- for the reason that the shuttle-race and reed move with the lathe inbeating up the weft. Where the shuttle-race is movable, the speed of theloom is limited, as the picker cannot act until the shuttle-race comesto rest in line with the box, while the imperfect registering of theshuttle race and box, which is likely to occur when said shuttle-race ismovable, causes the shuttle to be deflect-ed and leave the race. It willbe evident that these obj ections do not apply to our loom, in which theshuttle-race is stationary.

The lever K, which controls the adjustment of the lever L'for operatingthe box-cylinder, is actuated by means of cords or wires on m, whichusually lead from the opposite arms of said lever K to the Jacquardmechanism of' Jacquard has almost completed its movement; hence we findit necessary to use in our loom, in connection with the ordinaryJacquard mechanism, supplemental devices, whereby the necessary movementwill be imparted to the lever K at the proper intervals. This mechanismis shown in Figs. 2 and 3, in which N represents an arm hung to asuitable pivot-pin carried by brackets on the inner side of the frame ofthe loom and connected to one of the tails n of the Jacquard mechanism,bell-crank leversP P being hung to the same pivot-pin as the arm N, oneon each side of the latter, and being connected to tails p p of theJacquard mechanism.

The long arms of the levers P are prevented from dropping below the armN by reason of supporting-lugs s on the latter, and the short arms ofthe levers are provided with slides t, having projecting pins 2, theseslides being adjustable 011 the arms of the levers and being secured inposition after adjustment by means of suitable set-screws u.

Hung to a pin v, carried by a stud on the side frame A, is a lever S,the long arm of which is connected by a rod 4: to a crank-pin v on adisk S, which is secured to or forms part of a spur-pinion R, gearinginto a spurwheel R on the cam-shaft D or any other available shaft ofthe loom. (See Fig. 3.)

The short arm of the lever S carries a pair of levers T T, the long armsof which are connected, respectively, to the cords or wires m m of thelever K, the short arms of said levers T T projecting into the path ofthe pins t of the slides 15, carried, respectively, by the levers P P.

The levers P P can be lifted independently of each other by the tails pp when either lever is to act upon its corresponding lever T or T; orboth levers may be lifted simultaneously by means of the arm N when bothlevers T T are to be acted on to adjust the lever K to the mid orinactive position shown in Fig. 1, the extent of lift of the levers inthis case being less than when they are directly actuated, owing to thefact that the lifting-tail n of the arm N has more slack than the tailsof the levers P P.

It will be observed that the movement of the lever K is not due to thedirect action of the jacquard, but to the vibration of the lever S,which carries the levers T T, against the pins t of the levers P P, andthis vibration is so timed as to effect the operation of the lever Kduring the intervals between the operations of the shuttle-box slide H.

If desired, the arrangement shown may be reversedthat is to say, thepivot-pin of the arm N and levers P P may be carried by thevibratinglever S, the levers T T being hung to a fixed pivot. (See Fig. 7.) Thelevers T T might also be operated by direct contact with the arms of thelevers P P; but the use on the latter of the adjustable slides withstriking-pins is preferred, as it permits the extent of lift of thelevers T T to be readily governed.

The mechanism for operating the beatingup comb may be modified withoutdeparting 1. The combination, in a loom, of a fixed shuttle-race and anindependent beating-up comb and devices for operating the latter, a

shuttle-box slide guided onv the fixed frame of the loom and havingboxes carried partly by said slide and partly by a cylinder hungthereto, mechanism for raising and lowering the shuttle-box slide on thefixed frame, a notched fork for engaging with the cylinder and turningthe same as it is raised or lowered, and means for operating said fork,substantially as specified.

2. The combination of a shuttle-box slide having a cylinder hungthereto, means for operating said slide, a notched lever engaging withthe box-cylinder to turn the same, a dictating-lever connected to saidoperatinglever, Jacquard levers having operating-tails, leversintermediate of the Jacquard levers and the dictating-lever, cordsconnecting said intermediate levers to the dictating-lever, a movablecarrier for the Jacquard levers or intermediate levers, and means foroperating said carrier, all substantially as specified.

3. The'combination of the levers P P and their supportingarm,operating-tails connected to said arm andlevers, the lever K,intermediate levers T T, connected by cords to the lever K andconstructed for engagement with the levers P P, a lever S, carrying oneset of said levers, and means for operating said lever S, so as to carryits set of levers from and toward the other set, all substantially asspecified.
